Matthew Fitzpatrick and Michael Kim proved why they are the number one and two players on the World Amateur Golf Ranking with outstanding performances in the Walker Cup at the National Golf Links.

World number one Fitzpatrick turned in an impressive performance, winning three out of his four matches. His efforts proved in vain as the United States gained the cup with 17-9 victory. Kim, the world number two, won all three of his matches.

Cory Whitsett proved why he’s the world number three by compiling a 2-1-1-won/lost/halved record to help the U.S. cause. World number four Patrick Rodgers won two and lost two

There were outstanding performances too from players outside the top 10. Bobby Wyatt of the University of Alabama won three and a half points out of four. That’s one reason why Wyatt moves up three places on this week’s ranking to 24th.

Wyatt isn’t the only Walker Cup player moving up this week’s ranking. England’s Callum Shinkwin saw limited action in the Walker Cup, only making two appearances in the singles sessions. He lost his opening singles match but won his second. He moves one place on this week’s WAGR table to world number nine.

Michael Weaver of the United States takes an even bigger jump. He improves nine places to 13th. English players Jordan Smith and Amateur Champion Garrick Porteous both advance three places. Smith becomes he world’s 12th best amateur with Porteous moving to 15th. Jordan Niebrugge joins the top 20, climbing four places to 20th.

Ireland’s Gavin Moynihan was the youngest player in this year’s match. The 18-year-old played all four matches, winning two and losing two. He climbs 45 places on this week’s table to 88th.

The Women

World number one Lydia Ko usually steals the headlines when it comes to women’s amateur golf in New Zealand’s. Two of her compatriots earn significant headlines this week after winning important tournaments.

Chantelle Cassidy sees her World Amateur Golf Ranking improve after an emphatic victory in the Waikato Classic at Ngaruawahia Golf Club. Cassidy proved too strong for the rest of the field in posting rounds of 70, 71 and 74 for a 215 total. She led from start to finish to win by eight shots over Wenyung Keh.

Cassidy climbs eight places on this week’s ranking to 63rd to overtake world number 64 Lita Guo as the third best New Zealand woman amateur on the WAGR table.

Compatriot Julianne Alvarez solidified her position as New Zealand’s number two woman amateur with victory in the New Zealand Under 19 Championship at Templeton GC in Christchurch. Alvarez posted a second round of 70, 3-under-par, to take a three -hot lead into the final round. She returned a 1-over-par 74 for a level par total of 219 and a three-shot victory over Australia’s Shelly Shin.

Alvarez moves one place on this week’s WAGR table to 41st.

Sierra Brooks of the United States needed three playoff holes to win the AJGA Girls Championship after she tied for the 54-hole lead on 4-under-par 212 along with Kaitlyn Papp. Brooks, who held a three shot lead heading into the final round, holed a 25-foot birdie putt at the third extra hole to break the deadlock.
